Which best practice should be followed during backflow device testing?

Following manufacturer guidelines and local regulations is crucial during backflow device testing because it ensures that the testing process complies with the standards set for safety, effectiveness, and legal requirements. Each backflow prevention device has specific instructions provided by the manufacturer that outline how to properly test and maintain the device to ensure it functions correctly. Adhering to local regulations ensures that the testing is in line with community safety protocols and state or municipal laws, thus protecting public health and maintaining system integrity.

Testing at any time during the year may not take into account the ideal conditions or specific timelines established by local regulations or best practices, which may emphasize regular intervals based on seasonal factors. Only testing when requested by the property owner can lead to gaps in oversight, possibly allowing issues to go unnoticed until they become more severe. Restricting testing to only manual methods ignores advancements in technology and may not provide the most comprehensive evaluation of backflow prevention devices. Thus, aligning with both manufacturer guidelines and local regulations is essential for effective backflow device testing.
